Title: Detection of bacteria by nucleic acid hybridization, labeled probes and test kit therefore.
IPC: G01N33/58
Filed: 1984-08-03
Abstract: A nucleic acid hybridization method for detecting bacteria in a test sample, such as a mammalian body fluid, employing a polynucleotide probe having a base sequence which is homologous with at least one base sequence in the nucleic acid content of substantially all of the respective bacteria suspected to be present in the sample. The homologous base sequence in the probe preferably comprises at least a 10 base portion of one of the strands of a gene which codes for the synthesis of a nucleic acid or protein comprised in the mechanism of protein synthesis, e.g., tRNAs, rRNAs, and elongation factors. Resulting hybridization between the probe and single stranded nucleic acids released from bacteria in the sample indicates bacterial presence and can be detected by employing labeled probes or otherwise detecting duplex formation. The method provides a unique, direct and rapid means for detecting the presence of bacteria without the need for conventional microbiological culturing. In particular, the method can be applied conveniently as a screening test for bacterial presence in fluids which are normally sterile, such as urine or blood.

Patent ES-8703566-A1 (ES)
Title: Lock assembly.
IPC: E05B13/10
Filed: 1985-10-02
Abstract: A lock assembly has a lock barrel which slides in a housing so that a finger at the end of the barrel can release a latch. The lock barrel is prevented from sliding when the barrel is locked, by engagement of the finger with a blocking plate, but the barrel is freed when the key is inserted and turned. The finger is made so that it shortens if excessive axial force is applied while the barrel is locked. This shortening may be effected by including an easily rupturable connection between different sections of the finger. When the finger shortens, the connection ruptures and prevents the finger from getting near the latch to release it. Once the connection has ruptured, further movement of the barrel into the housing will bring the barrel into contact with the outer periphery of the blocking plate which is well supported.
